This expression has a kind of reaction inwardly which has an effect upon a person's body, upon his mind, upon his soul. There are certain parts in the human body which may be considered as the factors of intuitive senses, and when by voice, by word, by breath these parts are brought into action, brought to life, man begins to experience a fuller life. If that person is an artist, a musician, a writer, a creative genius, whatever he is, by cultivating all the natural faculties which are within him he can express his art or his science to the full.
